Spectral Logic Inversion Using Optical Wave Mixing.
Abstract
The main objective of the program is to utilize nonlinear optical wave mixing for spectrally parallel logic operations. In this program, we are investigating the parallel processing of information in the spectral domain. Specifically, we are investigating the optical implementation of spectrally parallel logic operations, including AND, XOR operations and logic inverter (also known as X-gates for set difference logic operations) using optical four wave mixing in nonlinear media such as photorefractive crystals, Kerr media. The spectral logic inverter, for example, can convert the spectrally encoded word of (1001) into a spectrally encoded word of (0110). In addition, we have also developed several new concepts in optical logic operations and optical computing. These include multiwavelength optical full adder with carry generation, multiwavelength full adder with polarization encoding scheme, modified signed digit arithmetic for multi-input digital optical computing, multiwavelength multiple beam splotters, optical fuzzy set reasoning, etc.
